To all whom itmtty concern:

Be it known that 1, ROBERT COOKE SAYER, a subject of the King of Great Britain and Ireland, residin at 11 Clyde road, Redland,

. Bristol, En lan have invented certain new and useful mprovements in Electric Transmission; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object is an electric railway with vehicles to travel over it so constructed as to secure rapid short-distance and express long-distance transmission for passen ers and goods able to be loaded and unloaded at the level'and directly from the pavements of densely-populated urban streets without danger to other or its own traific while being transmitted through and from urban districts and open country and across water to connect similar populations in other lands, and essentially it. consists of First. Two or more rails carried on opposite-sides of a tube, frame, or support. One or all such rails are formed with a head without projecting bolts, fish-plates, or other projecting parts, a closed tube in the head,.an electric conductor in the tube insulated on top by a ribbon able to rise and fall, parts of the mil-head made concentric to the fulcrum of levers that are carried on the surface of the rail by wheels or suspended from'a car and retained in place by other wheels that run against the concentric parts and are carried on the levers each side of the rail by parts able to more or less grip its head when the levers and the wheels are actuated laterally.

The levers carry an arm pointed at each end able to push aside, but keep closed, the parts closing the tube, so that conductors in the arm having wheel-contacts to run against the conductors in the, tube and'raise and thrust down the insulating-ribbon always connect to and from the motors: a car or body carried between the said rails by two connected wheels, each end having double flanges to guide them and able to swivel upon it and run upon or against the rails, so that the axis of the car produced will out a line between and connecting the centers of gravity of a pair of the rails. One, or nll the wheels, has a motor within it regulated by drawing its rotor more or-loss from or to its stator, and cushioned from vibration by the periphery of the wheel being separate from its center driving part that acts, against sprin s between them and carrying the whee more ,or less by the said wheels actin against the said concentric parts of the rail should either of the motor-wheels fail, and thus enables the'parts to fulfil the necessary conditions.

Second. Constructing the tube, frame, or support for the above said rails suspended above urban streets or in shallow subways below them close to their pavement and bringing them to the surface level of the pavement at fixed stopping-places, so that air may enter there and circulate through the subways.

Third. Constructing the tube, frame, or support suspended from floats in water by hollow jointed tubes able to supply the tube with air, jointing the rail-carrying tube by known means, so as to make it flexible in a 1 directions.

The object is attained as set forth by the following specification and drawingspwhere Figure 1 shows in. parts a plan of the tube or frame arranged for one side of urban streets; Figs. 2, 3, 4, 5, sections at A A, BB, C C, D D, on Fig. 1, having a datum Z Z; Figs. 6, 7, 8, cross-sections in open country: Figs. 9, 10, sectional elevations of the tube for tidal waters; Fig. 11, a section at E E, Fig. 9; Figs. 12, 13, a plan and elevation of the rail Fig. 14, a section at F F, Fig. 13. Fig. 15, a detail for insulating and picking up the current; Fig. 16, a section at G G, Fig. 15; Figs. 17, 18, a section and plan of the car: Figs. 19, 20, sections at H H, J J, Fig. 18, 0: the wheel.

The rapid-service cars a in open areas, Figs. 6 to 1]., run in the same tube or frame 2 and on the same rail it as the express-cars b, the speeds being similar. As the population increases, a and b run in separate tubes or frames 2 and pass one another in either direction, above, below, or laterally. For urban streets the frame 2 is suspended, Fig. 8, above or at the back of them, or below them, Figs. 1 to 5, but in all cases come to surface stopping-places c for a and (1 for b at either side of the pavcmcntc and buildings f that pedestrians may stop direct from c to a or 1) without danger from other trailic. For the cars I) to pass (1 and rise to the surface to (I the frame .2 is diverted laterally, .l igs. l, .2, undo, and brought into line again adjacent to the pavement e.

The cars a and b are carried over water areas he, 9, 10, 1.1 by the tube 2 being suspended from floats lL, connected by hollow jointed tubes ho to provide air, and at the land approaches and elsewhere when required for curvature the tube 2 is formed in lengths 22, connected by flexible joints hl) of known form for 22 to suecessively rest upon or be raised from Walls or the bottom 7w by the floats h as the tides fluctuate,(shown by dotted lines,) and the tube 2 is fixed by the bank hcl, except where steep gradients are admissible, Fig. 10. It is then carried by wheels 2%. The areas he are connected to urban districts by the tubes or frames 2, carrying the cars ab in hilly or flat parts, as shown by Figs. 6, 7 and over obstructions by Fig, 8.

In all cases the cars a?) are supported between the rails it, which are formed in crosssection, of two duplicate parts it and fis'h plate parts to without rojeo'tions externally at the head, a longitu inal key and parts it concentric to the center ya, on which levers j of known form and working are able to be moved laterally, and these parts are held together by bolts te. Thus a longitudinal hollow or tube 'lg is formed'and closed by soft longitudinal parts 41m and hard parts tn, thrust together laterally by springs "l0 to inclose an insulating-lining ih and electric conductors il.

The levers j carry an arm jb, Figs. 12 to 16, 20, upon their fulcrum-bolts y'a. It has elec tric conductors i 'll jlc, connecting with wheels 10 jd jc, that run upon the conductors ll j/r in the tube ig and with links id and the stator 0 of the motor, and the part of the arm jb, passing between the closing parts tm in of the tube '59, is pointed each end to it their curvature and keep t'g opened as the arm jl) passes on until closed again by the springs to.

The levers j have parts to to fit the rail it on each side and carry wheels id to run longitudinally against the two concentric parts it of the rail "Li and hold the levers j to it, and the wheels id traverse the parts i?) laterally when the levers j are moved to grip or be loosened from the rail it. The conductors t'j il carry positive currents, but of different pressure, and when required "ll is covered by an insulating-ribbon "Lp, having lugs t'q, that enter slots d1 of suitable length in the insulator ill, so that as the wheel jd passes along upon all it raises the ribbon lp and the lugs t'q in i7, and the ribbon M9 is thrust down again 'by the following part is of the arm 7?). The conductor y'lr carries the negative currents to the wheel jc.

The cars a 1), Figs. 1, 6 to 8, and 17 to 20, are carried by "the wheels la and their two flanges lrb upon and against the rails it. The

cars swivel upon-{ the wheels k at leg, as bogie cars, by known "means.

The wheels lc are formed of a peripheral part lca, having two flanges lab, lateral wheels [cc to run against fixed sides lm, explained below, recesses lrcc, and stops ltd l, carried on the strap lcdcg The wheel lr has an inner concentric part led with lugs cross-springs lce between two pairs of lcf, and springs lcg, carried in saucers lch, having arms lclch, projecting into recesses lC'CC. The springs lug have guiding-horns lcj, secured to the saucers lab, and lch normally rest against the lugs lrf and the stops Add, with their arms lt'lcll against the ends of the recesses lccc. These act in the left direction. Duplicate saucers lchll and attached parts act similarly against duplicate stops and the springs lrg to rotate the periphery lca in theopposite (right) direotion. The inner part lrclalsohas flanges lslc and teeth lcl. The wheel lr also has fixed sides lm, retained in place upon the part led by wheels la ma and the wheels lcc on the periphery lca and are connected by struts lcm to a bearing lm and lco with. a collar lap to support the axle nof the rotor 00, having keyways no and the pinion 121) to gear with the teeth lcl. The sides lm carry the stator 0 of the motor.

The motor is formed of any number of stator and rotor elements, one pair being shown, according to the power required. The rotor 00 has keys'oa in the Ways no to drive the axle at when raised to the dotted position or returned within 0 by turning the handle 1'), rod pa, pinions pl), and screwbolts pc to raise the parts pd and their wheels pe, on which the rotor 00 rests.

Working: The electric pressure is supplied to the rail conductors tl by known means and passes to the wheel-contacts y'c or jtl, arm jb, Fig. 16, the spindle ja of the levers 9', Fig. 14, the links id, and the stator 0 of the motor, Fig. 20, and the negative jlc is returned similarly byid j y'a jl) to the wheel jc and the conductor j/c, Figs. 14, 15, causing itsuntil lclcllmeet the ends of the recesses l'cc.

Then the periphery lca necessarily rotates with lcd, if not before; but the saucers lclzlz are left behind, thrust against their stops lxlzl andarms 'lclclt against the ends of their recesses lccc by the compression of the springslcg. The springs lce cushion the vertical and longitudinal motions, and the wheels lac rotate against the fixed sides land In to give them lateral motion. The wheels li' swivel to act as bogies andare thrust by known means against the rails it for traction purposes and carry the cars within the tube, frame, or support 2 from, say, a station a or (1, Figs. 1, 2, at the pavement of a street to descend rapidly to below. the street within .2, but close to the pavement 6, Figs. 3 to 5, to give room for drains (or to ascend and be suspended above the streets) and to rise (or fall) to other stationsc or cl and descend (or rise) again and reach open country, Figs. 6 to 8, and cross water, Fig. 9, by descending through the bank lid to the suspended tube 22 and z and rise similarly, Fig. 10, to other lands. The rotor 00 of the motor is given more or less power by drawing it to or from its stator, and the car is stopped and lirmly held independently of the wheels A by the brake iaws "is, Fig. 14, being made to grip the head of the rail it more or less by drawing the upper parts of the levers together laterally by known means and drag by the links id on the sides Zm. The car is normally carried each end on one wheel 7c. Should it fail, the Wheels M, Fig. 14, traversing the concentric surfaces i!) of the upper rail it, support it.
